Application led March 13,

To all whom t may concern :y y

4 a citizen of the United States, residing at Buifalo, in the ycounty of Erie and State of yNew York, have invented certain new and useful Improvements in Variable-Speed Counter-Shafts, of which the following, is a specification. v y

rlhe invention relates generally to improvements in variable speed countershafts, and more particularly to a structure in which the power from the Vdriving element is transmitted to the'drven element through a plurality'of simultaneously` controlled friction elements.

The main object of the present invention is the provision of a variable speed countershaft embodying duplicate simultaneously operated friction disks, the movement of the friction disks with relation to the adjacent disks cooperatingv therewith inducing the desired variation in` speed and being manually controlled through a simple, effective mechanism.. l y o y A further object is the provision of means for manually controlling the cooperation of the driving rfriction disk with the adjacent friction disk, wherebyto readily govern the starting and stopping of the variable speed mechanism.y y j The invention in its preferred formof details will be described in the following specification, reference being had k.particularly to the accompanying drawings, in

Figure 1 is a view `in elevation partly in section illustrating the improvemenn Fig. 2 is a bottom plan ofthe same. Fig.' 3 is an end elevation view from the drivenend. Fig. 4f is an end elevation viewwfrom the driving end. Fig. 5 is an enlarged section, partly in elevation illustrating the manually operated control means for the friction disk. Fig. 6 is a broken section partly in elevation through such control means, taken at right angles to the section ofFig. 5.

Referring particularly to the accompanying drawings, wherein the improved variable speed counter-shaft is shown as an overhead shaft, rkthe details comprehend a hanger l `including a kceiling plate 2 of appropriate size and strength designed to be bolted or otherwise secured to theoverhead support 3. Supporting beamsv 4 depend from the plate 2 and ,21179 olinedwithgor Specification of Letters Patent.

otherwise constructed to provide shaft bearings 5 at their lower ends. The beams 4 are connected by an intermediate strut 6 in parallelism with the ceiling plate and connected thereto by a web 7, a supporting beam 8 depending centrally from the strut and terminating on a plane above the bearing. The beams l are provided with outwardly and downwardly extending arms 9 and l0, the former of which in line with the bearings 5 is formed to'provide a bearing'll and extended below said bearing for a short distance and terminally provided with an interiorly threaded sleeve 12, while the arm 10 terminates in a bearing 13 in line with the kbearing 5.

The framework just described is preferably of integral l`onstruction and the various parts thereof, in so far as possible, constructedy of channel or angle formation to provide` the requisite strength.

The driving shaft 14: is mounted in the bearing 5 of the beam e adjacent the arm 9, the opposite yend of the shaft being mounted in the sleeve l5 supported in the bearing 114 and keyed to the shaft to prevent independent longitudinal movement of the sleeve and shaft while permitting their independent rotary movement. Keyed upon the driven shaft rlet is the driving pulley 16, said pulley being preferably arranged intermediate the bearings 5 and 11 and operated from any suitable source of power through a belt 17. Secured upon the relatively inner end of the driving shaft 14 is a friction disk 18, said disk operating in f a plane located inwardly of the adjacent beam 4.

Secured upon the outer terminal of the sleeve 15 is a block 19, the transverse dimen-y sion of which exceeds the diameter ofthe sleeve, the inner edges of the block beyond the sleeve being each provided with a p rojection 2O.y In advance of the projection 20, and in line therewithk the sleeve is provided with afdiametrically extended pin 21, the ends ofl which extend beyond the surface of the sleeve.

Pivotally mounted upon a lug 22 extending from the arm 9 above the bearing 13 is the manually operable control lever 23.

Patented Feb. 2, 1915.

This lever includes spaced armsy 24 con,

nected at their upper ends to yprovide a bearing plate 25, the arms extending on opposite sides of the sleeve and lying he 11o` vso tween the projections 20 and pin 21. Immediately below the projection 20 the arms are deflected vlaterally and then depend in parallelism with the extension of the arm 9 below the bearing, the lower endsof the arms being formed to provide guide eyes 26. A pressure rod 27 is slidably mounted in the horizontal portion of the arm 9 and in the beam 4, bearing blocks 28 being provided for the purpose. An extension spring 29 is coiled about, the pressure rrod bearing between one of the blocks 28 and a stop 30 adjustably secured upon the rod 27. The outer vend` of the rod bears at ally times against the plate`25 of the control lever 23 under the -action of the spring '29.

Threaded inthe sleeve 12 is an adjusting rod y31 which on the 'end adjacent the arms of the lever 23 is provided with a chain wheel 32, an endless operating chain coperating with said wheel for turning the same. and thereby adjusting the rod '31 lengthwise the sleeve 12. The operating chain 33 passes through the respective guide eyes 26 of the lever, and the end of the rod immediately beyond the wheel 32 bears against a cross bar 34 of the lever.

The construction at the driven end of the mechanism is practically identical with that described omitting the manual control, that is to say, the driven lshaft 35 is mounted in the bearings 5 andr 13, being provided intermediate their bearings with a driven vpulley 36 from which power is taken by a belt37. The relatively inner end of the driven shaft is provided with a friction disk 38 similar to .and in alinementwith the driven friction disk 18. The driven shaft is mounted at its outer yend in a sleeve 39 keyed to the shaft to prevent independent longitudinal movement while permitting independent rotary movement. .The outer end of the' sleeve is vprovided with a block 40, similar to the block 19 yatth'e driving end, said block having pronection with the manually operated control lever includes spaced arms, being positioned intermediate the. projections 41 and pin 42, while the uppery end loosely receives a vthreaded pin 45 bearing at itsy inner end against the block 46 secured to the arm 1 0 and provided at itsouter end with an operating head 47, and further provided with avr lock nut 48` designed to bear against the end of the lever.4 The threaded connection between the rod 45 and lever provides for setting the i ,driving shaft to at all times I'nairfr` tain operative engagement between the friction disk 38 and the adjacent friction ldisk as will presently appear.

The faaioa mches-isa intagli the pa-- anism includes a block 49 having upstandation of which the variable speed ofthe drivenshaft from ythe fixed speed `of the driving shaft isr obtained, is arranged intermediate the driving friction disk 18 and the driven y friction disk 3S. The friction meclr ingundercut edge flanges 50 adapted to cooperate with complementary formed yedges 51 of a bed plate 52 supported by the hanger beam 8 and extending at right angles to the plane of Athe driving and driven shafts. One of the flanges 50 is 'preferably provided with an adjustable wear plate 53 between it and the adjacent edge of thebed plate 52 wherejV by to take up wear of the parts and insure an even `sliding movement of the block 49 on the bedplate. The block is formed to provide a depending bearing 54, of any desired construction inwhich is supported what may be termed a lclutch shaft 55. This shaft is 'arranged at a slight 'angle to the plane of the driving 'and driven shaft, for a purpose which will presently appear. The respective ends of the clutch' shaft beyond the bearing 54 is provided with friction disks 56, each comprising annular wheel like sections having outstanding undercut edge' flanges' 57. An annular section 58 of appropriate material, for friction clutch purposes is securedagainst the outerV surface of the wheel', bearing against the flange 57 4and remoivably iXef'd/in placey by an annular holding member '59 secured to the wheel by screw bolts 60 and bearing against the relatively inner inclined edge 61 of the clutch member5`l8'.hV

The block 49 is provided with an upstand ingr abutment 62 having threaded bore extending longitudinally thereof as fat 63, the abutment working `in an appropriately formedchannel 64 provided in the bed plate 52. A Air adjusting shaft A65 is mounted in thenbed plate for independent 'rotary movementthough fi'Xed against longitudinal movement This shaft operates in thel channel V`6'4 and is threaded for coperation ywith the bore 63fof the abutment 62.

Oneend of the shaft "65 projects beyond the bed plate vand is provided with a vchain wheel 66 which an 'endles'sfoperatingchain 6 7 coperaties, said chain preferably passing through 4eyesof a guide member 68 hung uponth, Shaft- A Through the angularl yarrangement of the clutch shaft hereinbefore referred toit will be obviousthat lthe friction disks are angu!y larly disposed with yrelation to the respective frictionfdisks, whereby 'therespective friction ,disks pc'operate at diametrically op'-Y posedfpoints', Ias willY be noted from Fig. 2, thus securing balanced action in operati.

tional cooperation with the adjacent friction disk 56. The driving friction disk 18 is normally maintained in coperation with the adjacent friction disk through movement of the lever 23 under the influence of the spring 29, and if at any time it is desired to interrupt this connection, such result is readily obtained by properly operating the chain 33 to move the rod 31. laterally and thereby force the lower end ofthe lever 23 outwardly with the effect to move the friction disk 18 out of engagement with the adjacent friction disk.

To give the desired speed, and control the variation of speed the friction disks 56 are adjusted to and from the center of the friction disk, this vadjustment being accomplished by operation of the chain 67 to turn the shaft 65 and move the block 49 longitudinally of the bed plate.

What is claimed is l. A variable speed counter-shaft including a driving shaft, a friction disk carried thereby, a driven shaft, a friction disk carried thereby, friction mechanism arranged intermediate the respective friction disks, means for normally setting the driven shaft to maintain contact between the friction mechanism and friction disk carried by said shaft, and manually operable means for adjusting the driving shaft to control the cooperation of its friction disk and the friction mechanism.

2. An adjusting means for controlling the cooperation of clutch elements of a variable speed counter-shaft, including a driving shaft, a lever pivoted beyond the shaft, projections carried by the shaft between which the lever is located, a xture, a rod having threaded connection with said Xture and bearing against the lever, and means for turning the rod.
